T0 all whom it may concern: I

Be it, known that I JOHN Z. DUDLEY, a citizen, of the 'United States, residing at Lindale, in the county of Smithand State of Texas, have invented certain new and useful Improvements .in Hay-Presses, 1 of which the followingis a specification My invention has relation to an. improvement in baling presses and-in vsuch connectionit relates more particularly to the .arrangement and construction of the :means for operating the plungeruof the press whereby reciprocation of the plunger may be secured by the revolution of an arm or lever whereby a single or doublereciprocation of the plunger during a'single revolution of the arm or levermayzbesecured as desired.

The present form'of baling press isespecially adapted to be operated by horse power and in the carrying out of my invention, a crank shaft, arranged to reciprocate the plunger of the press, is turned by a long arm or lever, one end of the lever being secured to the crank shaft and the other end attached to the horse by rope or chain. It follows that the horse travels with the lever in a circle, the crank shaft is turned to reciprocate the plunger. A spring assists in withdrawing the plunger from the press.

The present invention resides more especially in the means whereby the arm or lever is connected with said shaft-said means being adjustable or convertible so that for a single revolution of the arm or lever the crank shaft may be either continuously rotated to give a single in and out motion of the plunger or the arm may be released from the shaft during the continuous rotary movement of the arm to permit the spring to return shaft and plunger to a position where a new stroke of the plunger takes place and the arm is thereafter locked to the shaft to thereby secure two movements to the plunger during a single, continuous rotation of said arm.

The nature and scope of my invention will be more fully understood from the following description taken in connection with the accompanying drawings, forming part hereof, in which,

Figure 1, is a top or plan view of a baling press embodying the main features of my invention;

Fig. 2, is a side elevational view thereof;

Fig. agis alon itudinal--sectional-view of the same;

Fig. 4,-is an end elevationa-lview; Fig. 5, isan enlarged horizontal sectional view taken on line 5.-5 of Fig.

Fig. 6, is a top or plan view'partly broken away to show' the: connection between the arm or lever and the crank shaft; and F ig..7, is a vertical sectionalview taken on line 7.? of Fig.6. I 1

Referring. to the drawings, 1 represents the packing box and 2 the plunger. "The plunger 2 is connected by link 3=with the crankla of avertically disposed crankshaft 5. This crank shaft 5"is suitablyzsupported by a bearing 5* in=the=base6of the press and a bearing? in'the frameWork'S extending above said base 6. Above the bearing '7, the shaft 5- is provided with'a ratchet-9 secured to the shaft and traversed as at 10 by an aperture or opening'for a purpose to be hereinafter described.

Suspended by frame 11 to swing on the shaft 5 is an arm orlever 12, the front or shaft end of the lever having two brackets 13 inclosing the ratchet 9 and traversed by said shaft 5. The brackets 13 form a pivotal support for a pawl 14, normally engaging the ratchet 9. A spring 15 fastened at one end to arm 12 or brackets 13 bears at its free end on the pawl 14 to hold said pawl in the teeth of ratchet 9.

A spiral spring 16 connects the plunger operating link 3 with the framework 8 and serves normally to pull said link 3 and pl unger 2 outward away from the box 1.

So far as described it is manifest that the lever or arm 12 when turned about the shaft 5 will, through said ratchet 9, turn the shaft approximately a half revolution or until the spring 16 is extended sufficiently to pull the plunger and link back to normal position.

The spring 16 thus draws back the crank 1 to initial position before said crank has passed its half revolution. This slipping backward or reversal of the shaft 5 is permitted through its ratchet 9 and pawl 14 connection with the arm or lever 12. In I one complete revolution of the arm or le ver 12 If itis desiredto have but one complete stroke to the plunger 2 for each revolution of said arm 12, a bolt 17 is. passed through the brackets 13 and the opening traversing the ratchet} arm or le ae thiis locked to the ratchet 9 and hence to shaft 5 and the spiral; spring. 16: cannot;
